While there are a lot of books available on network security, most of them take
the approach of focusing on the attacks, on the hacks, and responding to those
on a one-by-one basis. This book does just the opposite, focusing on a holistic
approach to protecting your entire network. It covers all seven layers of the
Defense in Depth (DID) Model, as well as other material not covered in any
other books. DID refers to a system of combining defenses to provide added
protection. Since there are then multiple barriers between the attacker and the
attacked, this increases the level of security, and increases the cost of the attack
to the attacker. The authors are two senior members of Microsoft's Security
and Business Technology Unit (SBTU), and are among the most sought-after
speakers for security conferences. With security being such a strong focus at
Microsoft, this book is destined to become the standard guide for all network
administrators and architects who want to have the most secure Windows
network possible.
Jesper M. Johansson, Microsoft's Senior Program Manager for Security Policy, is responsible for the tools Microsoft customers use to implement security policies, including the Security Configuration Wizard and Editor. A frequent speaker at leading security events, he holds a Ph.D. in MIS, as well as CISSP and ISSAP certification. Steve Riley, Senior Program Manager in Microsoft's Security Business and Technology unit, specializes in network/host security, protocols, network design, and security policies and processes. He has conducted security assessments and risk analyses, deployed security technologies, and designed highly available network architectures for ISPs, ASPs, and major enterprises. © Copyright Pearson Education.

Law #1: If a bad guy can persuade you to run his program on your computer, it's not your computer anymore.
Law #2: If a bad guy can alter the operating system on your computer, it's not your computer anymore.
Law #3: If a bad guy has unrestricted physical access to your computer, it's not your computer anymore.
Law #4: -If you allow a bad guy to upload programs to your Web site, it's not your Web site any more.
Law #5: Weak passwords trump strong security.
Law #6: A computer is only as secure as the administrator is trustworthy. Law #7: Encrypted data is only as secure as the decryption key.
Law #8: An out-of-date virus scanner is only marginally better than no virus scanner at all.
Law #9: Absolute anonymity isn't practical, in real life or on the Web. Law #10: Technology is not a panacea.
